Tod whom it may concern/i i Ij Be' it, known that I, ERASTUS HAMm'roN, a citiz'enof the United States, and a resident of thefeity offlhicago, in the county of Cook gland stat of .Illinois, have invented certainnevd-and useful Improvements Bottles;

andido hereby declare that the following is iii-full; clear, and exact description of the same,;reference beinghad'to the accompany n: ing drawings, and to theletters of reference marked thereomwhich form apart of. this This mventio'n relates to improvements in bottles, and morep'articularly to a bottle of.

that classu's'edf ins'upplying or delivering milk ,tothe trade. He'retofore in bottles of thisfcl ass it has only been possible to empty for remove the milk from the aperture through 1 the heck of the top of the b0ttle, and censezt? r: nuy,it has been impossible to separate e cream from the milk, as is often desired. Furthermore, in-milk-bottles as usually con- "structedthe bottom is hi her at its center than adjacentthe sides-of t e bottle, thereby forming a depression in which the remaining milkor impurities a 'ter the bottle has been emptied settle and adhere,- making perfect cleansing diificultand causing the bottles to :{soo'n' become unsanitary.

' 3o Theobject of, his invention is to provide a s mtary bottle or receptacle for milk or the ikeandin which the milk may be quickly w and readily drawn from the separated cream, caving-the latter in the bottle or receptacle. 5 .It'is afurther object of the invention to v, rovi'deamilk bottle or receptacle capable of being much more readily and easily cleaned than; similar devices as heretofore constructed.'-

'40 "The [invention consists in the matters provided at its top with the ordinary closure a, ,of' paper-board or any desired material. The'lower end of said bottle is provided with a downwardly-directed peripheral flange a which extends below the bottom a? suffiicientlyto form considerable spaco below the same. Saidbottom a as shown is concave 3 i s ecification of Letters reheat.

on its upper surface, thereby providing a gradual slope from the side walls to the cen ter, which is the lowest portion of the bottle toward which all the drain is directed. The bottemc is also provided with a central axial aperture a", in which any preferred form of closure may be rigidly but removably engaged; but, as shown in Fig. 1,'a closure'B, of cork, rubber, or other desired material, is employed and which is inserted from without the bottle.

if preferred, the closure for the apertures may be provided with a valve, as shown in Fig. 2, in which the bottle A is provided with a bottom (1 as before described, and rigidly engaged in the central apertures thereof is the closure (indicated as a whole by C) and comprising, asshown, a shell or sleeve c, of induratedrubber, metal, or any preferred material, adapted to fit closely within said aperture a5, and the upper end of which is flush with the upper surface of said bottom and tapered. or beveled inwardly, forminga valvesea t c. The lower end of said'sleeve 0 isprovided with an outwardlyedirected peripheral flange 0 adapted to engage the under surface of said bottomand limit the up ward, movement of said closure therein. Formed complementally \Vltll and adapted to engage on said valve-seat c is the valve C, provided with a downwardly-extending J stem 0", which passes through a guide or spider integral with said seat and is provided on the lower end the cot with a spring C", the 11 per .end of which said spic er a and the lower end thereof against a pin or other desired means 0 in said stem and normally acts to hold said valve rigidly upon its seat, thereby completely closing the bottom aperture.

The operation is as follows: Inasmuch as Y ,the bottom of the bottle or receptacle is concave on its upper surface, the lowest/point of the bottomis at its center, toward which the contents of the bottle tend to drain .andto" pass out of the central aperture aithereby' leaving no depression or corner in the bottle adjacent the walls to collect coagulated milk or other impurities and making it possible to Inasmuch as tliorouglilly cleanse the same. the closure fits tightly within said-central engages against aperture, itis evident that no leakage can pass the same, and when it is desired to re move the milk from the bottle in case the.

closure B is used it is only necessary to remove or partly remove the closure, when the milk may be drawn oil, leaving the cream in the bottle, which may afterward be drawn of? is released the valve will again close. When,

however, it is desired to clean the bottle, the entire closure may be removed, as before described, permitting the'contents of the bottle to be thoroughly drained therefrom Owing to the concave shape of the bottom all parts of the same may be readily reached in washing the-bottle, thereby making it impossible for impurities to remain, and obviously any preferred term of closure for the bottom aperture may be employed without departing from the principles of my invention. i

y I claim as my invention 1. I A device of the class described comprisi'ng a bottle having a concave inncr bottom surface and an outer bottom surface hollowed to form a thickened supporting-flange and havin a central aiertnre therclbroiwh a sleeve rigidly engaged in said aperture havmg a concave upper end llnsh vnh the top of said apcrture and ail'ording a valve-seat, a

peripheral flange on the bottom of said sleeve engaging tbc bottom of the bottle and limiting the upward movement of t he sleeve, a centrally apcrtnred gmdcway in said slcevc a slcm engaging in said guideway, a i beveled valve (:11 Ihc upper end lhereoi affording a valve-closure, a spring engaging the under side of said gnic-lcwn-y and normally holding the valve seated.

- erases 2. A device of the class described comprising a bottle having an inner bottom surface rounded at the edge and gradually tapering to the center, a hollow outer bottom surface having a centrally-thickened bearing-face provided with a central aperture therethrough, a sleeve engaged in said aperture having a flanged lower end adapted to seat against said bearing-face and a beveled upper end, an integral g'uideway in said sleeve, a stem engaged in said guideway havin its lower end enlarged, a pin'projecting om each side, of said stern, a rearwardly-beveled valve adapted to seat on said beveled sleeve and a spring engaged between said guide and pin adapted to normally hold the valve seated.

3. A device of the class described comprising a bottle having a concave bottom therein prtividcd with a central aperture opening therethrough, a removable sleeveadapted to lit tightly in said aperture and provided with an inwardly-beveled u per end, a peripheral flange onthe bottom 0 said sleeve a apted to engage the bottom of thabottle andllmit the inward movement of said sleeve, a cenu tral guide 1n said sleeve, a valve-stem movably engaged therein, a closure on the inner end of said stem adapted to seat on the beveled end of said sleeve, a transverse pin in the outer end of said stem and a spring engaged between said pin and said guide and'aotmg normally to hold the closure seated.

ln testimony whereof I have hereunto sub scribed my name in the presence of two subscribing witnesses.
